JAMES L. SMITH, OF TAUNTON, MASSACHUSETTS.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 752,716, dated February 23, 1904.

Application filed May 12, 1903. Serial No. 156,753. (No model.)

To all whom it may concern:

Be it known that 1, JAMES L. SMITH, a citizen of the United States, residing at Taunton, in the county of Bristol, State of Massachusetts, have invented certain new and useful Improvements in Oil-Burners; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains.

to make and use the same.

This invention relates to oil-burners, and

more particularly to that class wherein the oil,

is heated and thus gasified and is then mixed with air prior to combustion, the object of the invention being to provide a construction of burner wherein the admixture of gas and air will be thorough and the combustion will be complete, so that there will be an economical consumption of oil and an absence of carbon 1z1ng.

A further object of the invention is to provide against flooding of the burner and consequent waste of oil and danger of spread of the fire outside of the burner.

Other objects and advantages of the invention will be understood from the following description. h

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a top plan view of a burner embodying the present invention. Fig. 2 is a vertical section taken diametrically through the burner in the plane of two branches of the oil-feed pipe. Fig. 3 is a vertical section taken diametrically of the burner in the plane of two branches of the overflow-pipe.

Referring now to the drawings, the present burner comprises what may be termed a head 5 of cylindrical form and which is provided with a bottom 6, upon the upper surface of which and within the inclosure of the head are formed a series of vertical tubular projections 7, the bores 8 of which projection are continued downwardly through the bottom of the burner-head. Between the tubular projections are the interspaces 9, which intercommunicate, so that the upper surface of the bottom of the burner-head has a honeycombed formation.

The oil that is to be gasified and subsequently burned is admitted to the base of the burnerhead and is held between and surroundingthe tubular projections 7 the oil instead of lying in a free state being absorbed by or held in a body of sand 10, which is filled in between the tubular projections and reaches to a height just below the upper ends of the projections. The sand actsa's a wick and because of its refractoriness does not deteriorate in use, excepting as it retains the products of distillation or volatilization of the oil. When the sand has reached that state where it requires cleansing, it may be dumped out of the burner-head and other sand substituted. The oil is supplied to the burner-head through nipples 11, which communicate with the interior of the burnerhead through the side wall thereof at points below the upper ends of the tubular projections 7 the nipples being connected with a common feed-pipe 12, which surrounds the burner-head and which is provided with a regulating-cock 13, through the medium of which the supply of oil to the burner-head may be regulated.

In order that the burner-head may not be lflooded, so that the oil will run out through the tubular projections 7 when it is admitted to the burner-head too freely, an overflow-pipe 14 is provided having branches 15, which communicate with the interior of the burner-head through the sidewall thereof at points above "mitted to the burner-head, so that the sand is saturated, and the oil is then ignited, the sand serving as a wick to facilitate ignition of the oil. After the oil is ignited the chimney is put in place, and the draft through the chimney serves to draw air upwardly through the ducts or air-passages 8, which mixes with the gas from the oil and aids combustion.

Within the chimney 16 is placed a cylindrical core 17, which is hollow and which is closed at its bottom, this core being supported within the chimney concentric therewith and with its bottom spaced slightly above the ends of the tubular projections. Between the chimney and the core is a narrow interspace 18, through which the gas from the heated oil rises and in its passage combines with the air that is drawn through the air-passages, the gas finally burning at the upper end of thechimney.

What is claimed is 1. An oil-burner comprising a burner-head having spaced projections upon its bottom and air-passages formed through the projections, the spaces between the projections being adapted to receive oil, a pipe inclosing the burner-head, and communicating at different points with the interspaces to supply oil thereto, a circular pipe disposed below the burner and having upwardly and inwardly directed pipes communicating therewith and with the spaces between the projections below the upper ends of the projections to carry ofi excess oil, a pipe connectingwith the circular pipe to carry the oil therefrom, said circular pipe also forming a base for the burner, and a chimney removably connected with the burner-head and a core within the chimney.

2. An oil-burner comprising a burner-head having an oil-holding recess therein, a hollow base disposed below the head, tubular supports connecting the head and base and cornmunicating with the oil-holding recess and with the base, and an oil-supply pipe communicating with the oil holding recess at points below the points of communication of said tubular supports.

In testimony whereof I aifix my signature in presence of two witnesses.
